Non-interactive way of declaring devices

# 7 years ago
t-b	Hi, is it possible to declare a device via the command line? I would like to get the testing of my device servers automated. Declaring the device in jive is currently the step I have to do manually. Note: Using SQL on the database is only a last resort for me and not really nice.

nleclercq	Hi Thomas, A python script could be a good solution. The database device server exposes everything you need to implement the tool you need. I'm even sure that a pythonista from the community will attached a piece of code to this topic for you. N. Edited 7 years ago

zreszela	Hi, I think that tango_admin should be enough. `–add-server` option is also fine for adding devices to a device server already declared in the DB. $ tango_admin –help Usage: –help Prints this help –ping-database [max_time (s)] Ping database –check-device <dev> Check if the device is defined in DB –add-server <exec/inst> <class> <dev list (comma separated)> Add a server in DB –delete-server <exec/inst> [–with-properties] Delete a server from DB –check-server <exec/inst> Check if a device server is defined in DB –add-property <dev> <prop_name> <prop_value (comma separated for array)> Add a device property in DB –delete-property <dev> <prop_name> Delete a device property from DB –tac-enabled Check if the TAC (Tango Access Control) is enabled –ping-device <dev> [max_time (s)] Check if the device is running –ping-network [max_time (s)] [-v] Ping network Cheers, Zibi

Hi,

$ tango_admin –help

Usage: 
 –help                 Prints this help 
 –ping-database        [max_time (s)] Ping database 
 –check-device <dev>    Check if the device is defined in DB
 –add-server <exec/inst> <class> <dev list (comma separated)>   Add a server in DB
 –delete-server <exec/inst> [–with-properties]   Delete a server from DB
 –check-server <exec/inst>   Check if a device server is defined in DB
 –add-property <dev> <prop_name> <prop_value (comma separated for array)>    Add a device property in DB
 –delete-property <dev> <prop_name>   Delete a device property from DB 
 –tac-enabled Check if the TAC (Tango Access Control) is enabled
 –ping-device <dev> [max_time (s)] Check if the device is running
 –ping-network [max_time (s)] [-v] Ping network

Cheers,
Zibi

sergi_rubio	PyTango provide all the methods to do so from the python shell. The fandango api provides a single command to create devices and assign them properties `import fandango as fn fn.tango.add_new_device('Server/Instance','Class','your/device/name') fn.tango.put_device_property('your/device/name','Property','Value')` You can also call them from shell: `:> fandango.sh add_new_device Server/Instance Class your/device/name :> fandango.sh put_device_property your/device/name Property Value` To start it on any host managed by Starter: `:> tango_servers yourhost start Server/Instance` Keep on dancing, http://www.tango-controls.org/resources/howto/how-fandango/ Edited 7 years ago

nleclercq	Holà Pythonistas! I now know what tango_admin is made for N.

t-b	Thanks all! I knew there is something already available. I'll try tango_admin and report back if there are any issues.
